door groups don't work

I have door groups for police/government jobs but nobody of that job group can lock/unlock doors.

Code (Text):

--[[---------------------------------------------------------------------------
Door groups
---------------------------------------------------------------------------
The server owner can set certain doors as owned by a group of people, identified by their jobs.

HOW TO MAKE A DOOR GROUP:
AddDoorGroup("NAME OF THE GROUP HERE, you will see this when looking at a door", Team1, Team2, team3, team4, etc.)
